无法将Android CalendarView更改为另一个月(Samsung S Duos - Android 4.2.2)

时间:2016-06-09 20:08:23

标签: android calendarview

Android在API 11中引入了CalendarView。我已经在我的应用程序中实现了它,它似乎工作得很好,因为它显示了一个完全正常的整月日历,我可以选择一个日期。它会触发相应的事件,我可以在我的代码中读取所选日期,没有任何问题。

但是我无法将其推出当月!文档说

  

用户可以通过点击来选择日期,并可以滚动和投掷日期   日历到期望的日期。

(“录音”出现在文档中;我认为这是“点击”的错字)

我尝试过投掷,滑动,滚动,没有任何反应。我需要做些什么来启用此功能吗?

我的XML看起来像这样:

编辑:
对于漫长的XML很抱歉 - 在我原来的帖子中,我只使用了CalendarView,但有人请求了整个XML。

另外要排除它可能是我在Samsung S5(Android 5.0)上测试过的设备所独有的可能性,并得到了相同的结果。

答案 0 :(得分:2)

根据我的假设,它不会因为可滚动的父级而滚动或投掷,你可以在没有滚动视图的情况下进行检查吗?

因为我用

测试了它
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
    <CalendarView
    android:id="@+id/debulkcalendar"
    android:layout_width="match_parent"
    android:layout_height="240dp"
    android:minDate="01/01/2016"
    android:maxDate="11/30/2016"/>
</LinearLayout>

及其完美的工作

您可以使用NestedScrollView

  

NestedScrollView就像ScrollView,但它支持表现为   新旧版本上的嵌套滚动父级和子级   Android版默认情况下启用嵌套滚动。

@RBK是对的,你的parentView(ScrollView)干扰了它的childView(CalendarView),这使你的CalendarView不可滚动。但是,您可以创建自定义CalendarView,扩展基础CalendarView类并覆盖onInterceptTouchEvent方法以获得所需内容。

创建自定义CalendarView类:

public class CalendarViewScrollable extends CalendarView {

    public CalendarViewScrollable(Context context) {
        super(context);
    }

    public CalendarViewScrollable(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CalendarViewScrollable(Context context, AttributeSet attrs,
                              int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        if (ev.getActionMasked() == MotionEvent.ACTION_DOWN) {
            ViewParent p = getParent();
            if (p != null)
                p.requestDisallowInterceptTouchEvent(true);
        }
        return false;
    }
}

在XML布局文件中使用它:

<com.example.app.views.CalendarViewScrollable
 android:id="@+id/debulkcalendar"
 android:layout_width="match_parent"
 android:layout_height="240dp"
 android:minDate="01/01/2016"
 android:maxDate="11/30/2016" />
